I am new here and please forgive me if this has already been answered and a push in the right direction would be greatly appreciated. I have recently purchased an M2 Revision F. The revision is so new that none of the technical info is up on the site anywhere yet. I am new to 3D printing and have had my ups and downs with learning but have quickly produced great quality prints. I should mention that this is being used for the company that I work for which is based in civil engineering. Once the prints were looking great, I had been tasked with upgrading to the dual extrusion to inlay the roads on the white model for better representation. Dual extruder was ordered and installed but the M2 REV. F is so new that Makergear had to generate new firmware because I am the first to do this with the Revision F model. Up until now, I have been using the quickstart app for all the printer preps and various slicers such as cura, slic3r, and ideamaker. My issue now is that I do not have a way to prep the new extruder such as loading and retracting filament because the quickstart app only has controls for 1 extruder. I can get the second extruder up to temp with the Geee LCD screen but I would prefer to do all of this via software. Any recommendations of software that will achieve these simple but needed actions?

Thanks Airscapes. I did also put in a help ticket to the Makergear wizards and they suggest the same. They also recommend Pronterface if I am looking to go the freeware route. I am trying to put together a case to present to me supervisor on way purchasing S3D would be beneficial.

That is simple
S3D is the manufactures (MakerGear) recommended software.
S3D is a supported paid product
S3D is only $150 and at this point and does not have a recurring support cost.
S3D will be releasing an update in the near future so you will have the latest and greatest.
